GLAZING APPARATUS.

Specication of Letters Patent.

Patented Dec. 28, 1920.

Application filed July 18, 1919. Serial No. 311,749.

To all whom it may concer/n.'

Be it known that I, STEPHEN A. Kos'r, a citizen of the United States, residing in Buffalo, in the county of Erie and State of New York, have invented new and useful Improvements in Glazing Apparatus, of which the following is a specification.

This invention relates to an apparatus which is more particularly designed for applying glazing material to a window sash for securlng glass panes thereon, although the device may also be used for analogous purposes.

The object of this invention is to provide a simple and inexpensive means for this purpose which can be readily operated by the use of one hand, which vcan be readily filled and conveniently operated for discharging the entire contents of the device upon the surface intended to receive the same, and which can be easily dismembered for inspection and cleaning.

In the accompanying drawings:

Figure 1 is a longitudinal section of my improved glazing apparatus showing the plunger in the rearmost position within the barrel and the valve at the front or outlet end of the barrel closed. Fig. 2 is a side elevation of the same taken at right angles to Fig. 1. Fig. 3 is a rear end view of the apparatus shown in Figs. 1 and 2. Fig. 4 is a side elevation, partly in section, of the glazing apparatus showing a modified form of my invention. Fig. 5 is a rear end view of the same. Fig. 6 is a side elevation, partly in section, showing another modification of my improvement. Fig. 7 is a rear end view of the same. j

Similar characters of reference refer to like parts throughout the several views.

The form of glazing apparatus shown in Figs. 1-3 is constructed as follows:

10 represents the barrel or cylinder of the l apparatus which is adapted to contain the supply of glazing material or other substance which` is to be deposited, this material being usually of semi-fluid character. At its front end this barrel is provided with a reduced delivery nozzle 11 forming an outlet through whichl the material is entirely discharged from the barrel. This outlet may be controlled by a valve of any suitable construction, that shown in the drawings being preferred and constructed as follows :u

12 represents a valve rod or stem which .slides transversely in a guide opening which 1s formed in the nozzle so as to intersect the outlet therein and which is provided with a port 13 so that upon moving this valve stem inwardlv the port 13- will be caused to register with the outlet of the nozzle and permit the material to escape from the barrel while upon moving this valve stem outwardly so that its support is out of register with the outlet passage in the nozzle, as shown by full lines in Fig. -1, then the escape of material from the barrel is arrested. The inward or opening movement of the valve stem is preferably effected by means of a hand lever 15 which is pivoted at its frontend by means of a pin 19 on an adjacent partl of the nozzle 11, while its intermediate part is provided with a longitudinal slot 18 which receives a pin 17 on the outer end of the valve stem. The outward movement of the valve stem is preferably effected by means of a spring 16 surrounding the valve stem and bearing at its opposite ends against the inner side of the hand lever 15 and adjacent outer surface of the discharge nozzle. The outward motion of the valve stem under the action of the spring 16 is preferably limited by a stop device consisting of a screw nut 14 mounted on that end of the valve stem which projects from that side of the nozzle opposite to that which is engaged by the spring 16, said stop nut being adapted to engage the adiacent surface ofthe nozzle when the valve is in its closed position. y

Movable lengthwise within the barrel is a plunger or piston, which during its forward movement, is adapted to discharge the material from the barrel through the front outlet of the same when it is open. This plunger may be variously constructed, but in the preferred form shown in the drawings the same comprises a cup shaped packing 20 of leather or other. suitable material which engages its peripheral portion with the front end of the barrel and two metal retaining plates or disks 21, 22 engaging with the front and rear sides of this packing.

23 represents a longitudinal shifting rod which is secured at its front end to the central part of the plunger while its rear part is provided with an external screw thread. The connection between this shifting rod and the piston may be produced in various ways, for instance, by providing the front end of this rod with a reduced portion which wardly and eject the material from the barrel when the valve forming the outlet at its front end is opened and the tension of the springs 36 and 38 is exhausted the same may be retensioned for restoring the automatic operation of the apparatus by simply turning the screw nut 35 so as to move the same backwardly on the shifting rod 23 to the desired extent.

All of the several constructions of glazing apparatus herein referred to are very eilicient in operation and capable of being easily manipulated and also quickly lilled and put in operative condition so as to facilitate the operation oi glazing and reducing the cost of the same accordingly.

l claim as my invention:

l. A glazing apparatus comprising a barrel adapted to contain a charge of glazing material and having an outlet at its front end, a valve for controlling said outlet, a plunger movable lengthwise in said barrel, a screw threaded shifting rod connected at its front end with said plunger, an ad'usting screw nut arranged on said shitting rod, and resilient means which receive the rearward thrust of said screw nut as the same moves away from the plunger and' which are operatively supported from said barrel.

2. A glazing apparatus comprising a barrel adapted to contain a charge of glazing material and having an outlet at its front end, a valve for controlling said outlet, a plunger movable lengthwise in said barrel'- a screw threaded shifting rod connected at its front end with said plunger, an adjusting screw nut arranged on said shifting rod, a spring bearing with its front end against said nut and adapted to be vflexed upon movin@r said nut away from said plunger, and an abutment for the rear end of said spring operatively connected with said barrel.

3. A glazing apparatus comprising a barrel adapted to contain a charge of glazing material and having an outlet at its front end, `a valve for controlling said outlet, a plunger movable lengthwise in said barrel, a screw threaded shifting rod connected at its front end with said plunger, an adjustysai ing screw nut arranged on said shifting rod, a spring bearing with its front end against said nut and adapted to be iexed upon moving said nut away from said plunger, and a yoke which is engaged by the rear end of said spring and which is connected with said barrel.

4. A glazing apparatus comprising a barrel adapted to contain a charge of glazing material and having an outlet at its front end, a valve for controlling said outlet, a plunger movable lengthwise in said barrel, a screw threaded shifting rod connected at its front end with said plunger, an adjusting screw nut arranged on said shifting rod, a spring bearing with its front end against said nut, and a yoke which is engaged by the rear end of said spring and which is pivoted on said barrel so as to be capable of swinging laterally.

5. A glazing apparatus comprising a barrel adapted to contain a charge of glazing material and having an outlet at its front end, a valve for controlling said outlet, a plunger movable lengthwise in said barrel, a screw threaded shifting rod connected at its front end with said plunger, an adjusting screw nut arranged on said shifting rod, a s ring bearing with its front end against nut, and a yoke which is engaged by the rear end of said spring and which is detachably connected with said barrel.

6. A glazing apparatus comprising a barrel adapted to contain a charge of glazing material and having an outlet at its front end, a valve for controlling said outlet, a plunger movable lengthwise in said barrel, a screw threaded shifting rod connected at its front end with said plunger, an adjusting screw nut arranged on said shifting rod, two coupling pins arranged 0n opposite sides of said barrel, and a yoke having a cross bar which 'engages with the rear end of said spring and is provided with an opening which receives said shiftin rod and two arms projecting forwardly rom oppo- -site ends of said cross bar and each prosaid pins.
